ICE-CREAM SPOON.

Specification of Letters Patent.

Patented Aug. 28, 1917.

Application filed January 6, 1912. Serial No. 669,903.

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to in ice cream spoons.

The object of the invention is to provide economical and simple means for disengaging the scraper from the bowl of the spoon for conveniently cleaning or repairing the parts.

The invention comprehends improvements in the details of construction and arrangement of parts.

In the drawings:

Figure 1 is a perspective view of my im proved spoon, the parts being assembled in operative position.

Fig. 2 is a plan view illustrating the position of the parts when disconnecting the scraper from the bowl.

Fig. 3 is a transverse section on the line 3-3 of Fig. 2.

Fig. 4: is a detail perspective view of a portion of the handle and the finger operat ing element.

Fig. 5 is a section on line 5-5 of Fig. 3.

1 indicates a handle on the end of which is secured a bowl 2. The end of the bowl is provided with an extended housing 3 formed with a centrally disposed opening 4C, the upper part of which is restricted by an overhanging flange 5. A lateral slot 6 communicates with the restricted part 7 of the open ing 4 to afford means for disconnecting the scraper.

Fitting in the bowl 2 is a scraper 8 on the end of which is a pinion 9 formed with a trunnion 10. The pinion 9 fits in the opening 4 and the trunnion 10 passes through the restricted opening 7. Extending laterally from the trunnion 10 is a lug 12 de signed to pass through the lateral slot 6 when removing the scraper and supported improvements on the flange 5 when the parts are assembled.

Extending from the handle 1 is an car 15 from which extends a post 16. Mounted on the post 16 is a finger operating lever 17 provided with an arm 18. Depending from the finger operating lever 17 is a hub and from the arm 18 depends a lug 19. A spring 20 is coiled around the hub and has one end fastened to the car 15 and its opposite end is fastened to the lug 19, the tension of the spring being such as to normally draw the arm 18 in the direction of the free end of the handle. This movement however, is limited by a stop 21 on the handle so as to prevent the spring turning the finger piece so far that parts would become separated.

Pivoted to the arm 18 is a rack bar 22, the forward free end of which fits in a longitudinal opening 23 in the housing 8. This opening intersects the opening i, so that the teeth of the rack bar mesh with the pinion 9.

Extending through a threaded opening in the car 15 is a screw 24L the upper end of which, when screwed upwardly (as viewed from Fig. 1) will be in the path of movement of the lug 19 and forms a stop to limit the movement of the finger operating lever.

When the lug abuts against the screw the lug 12 is out of alinement with the lateral slot 6 and thereby supports the scraper in operative position in the bowl. When the finger piece 17 is pressed toward the handle, the parts are so proportioned that the rack cannot turn the scraper far enough to bring the lug into registry with the slot so that so long as the screw is in operative position the scraper cannot be removed.

To remove the scraper, the screw is withdrawn from the path of the lug 19 and the spring will upon release of pressure on the finger piece turn the latter until the lug abuts against the stop 21. At this time the rack bar has turned the pinion to the position shown in Fig. 2, and the lug 12 registers with the lateral slot 6, and the scraper will fall from the bowl.

To assemble the parts, the scraper is inserted in the bowl and the pressure is applied to the finger piece and the latter is turned sufficiently to move the lug 19 past the screw 24. and then the latter is turned to bring its end into the path of said lug.

YVhen the scraper is removed the stop 21 prevents the rack being entirely withdrawn from the opening 23 and the spring throwing the finger piece so far around as to dislodge the spring from the ear.

To insure of the parts being in proper position when fitting the scraper in the bowl, the end of the free rack is provided with an elongated tooth 30, and the pinion 9 has several teeth omitted to form a space 31 between adjacent teeth to correspond to the Width of the tooth 30.

The stop 21 limits the movement of the rack bar 22, and brings the tooth 3O opposite the lug 12, consequently when the scraper is inserted in the bowl the tooth 30 and the space 31 on the pinion register and the lug 12 registers with the slot 6. This absolutely insures of the parts being properly positioned topermit quick and ready assembling of the parts.
